Yosemite National Park Safety

How safe is Yosemite National Park? Yosemite being a natural park, this question frequently occurs in tourists’ minds.

While visiting this beautiful yet challenging park, it is important to be careful and follow the safety precautions for Yosemite National Park. 

Here are some things to remember while traveling to Yosemite National Park.

You must avoid getting too close to the water at the peak of a waterfall and keep your distance from any slick rocks by the river.

Be prepared for sudden weather shifts. Carry sufficient layers, including raincoats. 

Snowfall is possible year-round; drenching thunderstorms may occur in a few hours.

Flowing water can appear deceptively tranquil. Be careful; even a meandering river could instantly carry someone away.

During mid- to late-afternoon, summer storms frequently produce heavy rain, hail and lightning strikes.

Plan to leave high open regions and cross passes around lunchtime. 

Avoid regions with water, open spaces, ridges, peaks (especially Half Dome) and caves during a storm. 

To protect yourself from lightning strikes, avoid towering, lone trees and look for cover in low-lying forests. Establish your tent in a secure area.


Hiking Yosemite National Park – START HERE (Beginner Tips)

To hike safely in any wilderness, you must be aware of your personal limitations and pack the appropriate clothing, footwear, food and drink. 

You will find all kinds of walking trails over 800 miles in Yosemite, on paved paths to steep, rocky cliffs without guardrails. 

You can hike on summer trails to view heavy downpours of North America’s most stunning and highest waterfalls, gigantic sequoia trees and ski or snowboard during the winter.

Adventures are many, but so are the risks.

Make a plan before hiking and study trail maps to keep yourself and your hiking companions safe. 

About 250 emergency situations in the park require the assistance of park rangers and search and rescue workers every year.

Yosemite’s Search and Rescue (YOSAR) spends most of its time helping hurt hikers or looking for lost persons in the wild.

Consider the following simple Yosemite National Park safety tips while hiking.

  • Always have a flashlight, especially for short day treks.
  • Carry and consume lots of water. One quart of water every two hours is recommended. In the scorching heat of the summer, carry more than you think you might need. 
  • Use strong shoes with excellent grip, and pack an extra pair if one breaks.
  • Know your limitations and consider how you feel when trekking up the steep valley routes since minor/moderate health or medical conditions can easily worsen.
  • If you are hiking with another person or in a group, you must carry some food and water with you if you are separate from your partner/group. 
  • If you are traveling alone, inform someone about your plans and details of when you will return.

Keep your distance from any wildlife, especially bears. 

The biggest concern while in the Yosemite wilderness is the black bear. 

Follow the Yosemite National Park bear safety rules to protect yourself, your food, your pets and the bear.

Even though wild bears aren’t usually dangerous, you should know what to do if you encounter one.

Keep your food away while hiking, camping or picnicking in Yosemite National Park.

The most crucial requirement for keeping animals safe in Yosemite is properly storing your food. 

Human food is not healthy for wild animals like black bears and when frequently fed excess food, they can start to act aggressively. 

This forces rangers to kill them if they threaten humans.  

Follow basic food storage and bear security regulations to prevent this.

Observe and follow the posted speed restrictions throughout the park.

Speeding automobiles hit numerous bears and hundreds of other animals every year.

While there is a need to protect the large animals, there is a greater need to be protected from the seemingly tiny animals, including mosquitoes, ticks and bacteria.  

You must wear and/or carry some kind of insect repellent. 

Use a bug spray and reapply as necessary because mosquitoes and ticks can spread infections.

If there is an emergency of any kind, call 911 as you would anywhere.

Be ready for emergencies by keeping a first aid kit on you and being familiar with its use. 

Be aware of your limitations and respect them to prevent potentially risky and expensive rescue operations.

Remember that most wilderness regions lack mobile phone reception, and not all locations support satellite phones.

You are responsible for letting someone know where you are going and when you plan to return since rangers do not keep track of wandering hikers.

The National Park Service’s Search & Rescue Team helps lost, stranded and wounded park visitors.

Here are some general Yosemite National Park safety rules to reduce your risk:

  • Use the phone number for the park’s emergency communication center, 209/379-1992, if someone has not returned from their scheduled return.
  • Stay on the trail; hiking off the beaten path raises the risk of injury or getting lost while seriously damaging the sensitive environment and creating severe erosion.
  • If you are on an unmarked trail, signal for help using a mirror or other reflecting item and stay put. A signal repeated three times in a row is a universal distress call.
  • Try to locate yourself using a map, compass and landmarks if you need help or direction.
  • Send a group member or a fellow hiker for assistance if you become unwell or hurt on the path and cannot continue hiking.
  • To secure the proper emergency response, note and provide the messenger with your precise location, age, gender, height, weight and a description of your illness or injury.


Some Yosemite diseases you must be aware of to protect yourself and others in the wild include

  • A serious, occasionally deadly respiratory condition, Hantavirus Pulmonary Syndrome (HPS), is brought on by contact with a virus-infected rodent’s saliva, urine or droppings.

You must keep your food securely packaged. Use a sleeping surface like a cot, at least 12 inches from the ground if you stay in a tent cabin, rather than putting the food down on the floor.

Properly dispose of your trash, and rather than cleaning up any signs of mouse activity,  alert park officials if you notice it in your accommodation or another facility.

  • Plague is a highly contagious bacterial illness that mostly affects rodents. You can contain it after contacting wild rodents that may be naturally infected with the plague. 
  • An uncommon but dangerous condition known as tick-borne relapsing fever (TBRF) is brought on by bacteria that soft ticks carry. 

TBRF frequently produces flu-like symptoms. After a few days, the symptoms come again or relapse a few days later.

  • Plague is a highly infectious bacterial disease primarily affecting rodents. Humans and other animals can get plagues if they visit or live in areas where wild rodents are naturally infected.
  • Ticks carrying the Lyme disease bacteria can cause Lyme disease.

Inform your doctor that a tick bit you if you develop flu-like symptoms after the bite.

  • A water-borne protozoan, Giardia lamblia, causes the intestinal condition known as giardiasis, which can lead to symptoms like chronic diarrhea, stomach pains, bloating, exhaustion and weight loss.  

Boil water or melted snow before consumption, or use an iodine-based/Giardia-rated purifier. 

  • Another deadly disease to watch out for is Rabies. This virus often enters people through the bite of a rabid animal. 

A rabid animal becomes violent and may attract humans, passing the virus that attacks the central nervous system.

Don’t touch any mammal you see acting strangely, especially raccoons, skunks, foxes, coyotes, or bats. Report the animal to a park employee instead. 

A full staff at the Yosemite Medical Clinic, between Yosemite Village and The Ahwahnee, assists visitors by caring for the sick and wounded.

Ask your doctor to contact the park sanitarian at 209/379-1033 if you are diagnosed with Lyme disease Yosemite or relapsing fever and you think you acquired it there.
